I've become very good at tearing and twisting up paper towels in many different ways to facilitate removal of excess liquid from my tanks and batteries.
What's your new skill?
Rationalising. Definitely.

learned how to burn through money like a drunken sailor
My day job for 36 years before retirement was troubleshooting and repairing my company's equipment in customers' offices. When I was a teenager I was always tinkering with electricity and mechanical devices. Most of the tech inside ecigs is every day stuff when it's what you do for a living.
When I started vaping, an ecig was a plastic cartridge with some cotton inside. You pulled it out and dripped some juice inside, then pushed it back in where the soaked cotton contacted a coil with a mesh bridge on it. The cotton saturated the mesh and the coil heated it to make vapor. Every half hour, you pulled the cartridge and soaked in again with juice.
This is what you had to do to fill your ecig 4 years ago. There were no tanks. Cartos came later.
This is the first thing I had to learn.
